discoloration on black screens

[_Zguy__]

On my screen there has been the slightest discoloration when displaying pure black. There are darker than normal spots on the top left and bottom left corners. Only visible on complete black and at night
should I be worried

No, this is typical of Super Amoled screen technology. Some displays exhibit it more, some less. That's just the way it is (unfortunately) also the quality assurance in Samsung really sucks, you will see these spots on almost any SAmoled Samsung phone.

No its normal, amoled displaya dont use backlighting they rely on blacks, thats why those blobs are only visible in the dark. Its a beautiful display compared to retina.
